Explain how different states of matter are distinguished from each other and how pure substance distinguish from mixtures

Hello

The difference between the states of matter is explained as follows:
- a solid has a definite shape and a definite volume
- a liquid has a definite volume, but its shape changes depending on its container
- a gas does not have neither a definite volume nor a definite shape: both change depending on the container. In fact, a gas expands until it occupies the whole volume available.

The difference between a pure substance and a mixture is:
- a pure substance has a precise and definite chemical composition
- a mixture, instead, is a combination of two or more substances.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
